The transition form factors of the semileptonic B→D2∗​(2460)ℓνˉ(ℓ=τ,μ,e) decay channel are calculated
within the framework of the three-point QCD sum rules. The fit functions of the
form factors are then used to estimate the total decay width and branching
ratio of this transition. The order of branching ratio shows that this channel
can be detected at LHCb.Comment: 15 Pages, 4 Figures and 5 Table
